Description
Introduction
ZHENJIN REFRACTORIES founded in 1985. It is a manufacturing enterprise integrating research and development, productions, sales, international trade and technical services. Refractory products and services for cement, lime, non-ferrous, glass, building materials and metallurgical industries.
Fused semi-recombined magnesia-chrome bricks are refractory products fired from part of fused magnesia. The main mineral composition of semi-recombined magnesia-chrome bricks is periclase, spinel and a small amount of silicate. The crystals are directly combined with periclase-periclase or periclase-spinel, and the thermal shock resistance of semi-recombined magnesia-chrome bricks is better than that of directly bonded magnesia-chrome bricks.
